Hi all, @Jacque:
I can successfully play .m4a audio files on Windows 7 using LC 8.1 dp3 *after* installing the LAV filters suggested in the LC Forums: http://forums.livecode.com/viewtopic.php?f=18&t=27380 Note that this is not officially suggested by LiveCode Ltd, it is just a working solution. @Peter: Player callbacks are supported in LC 8.1 dp2 onwards: https://github.com/livecode/livecode/pull/4140 So you can try them in 8.1 dp3 which is more stable than dp2. Just one thing to note: The Windows DS player uses different timescale, so e.g the same video might have a 1200 duration on OSX and 15200 on Windows (the numbers are completely random). So when you set the callbacks do *not* use an absolute value for the time, but relative to the player duration. Best, Panos -- On Sat, Aug 13, 2016 at 10:57 PM, J.
